PM320E

4   Remote Operation

ThePM320E optical power meter has a USB 2.0 interface that allows to send commands from
a host computer to the instrument. The connection between PC and PM320E is accomplished
by a USB cable with a male type ‘A’ connector at the PC side and a type ‘B’ connector on the
instrument side.

There are two categories of command types:

·

Set commands that bring the PM320E to the desired configuration

·

Query commands that get data from the PM320E. These commands are always
terminated by a question mark (?).

4.1   Connecting a Computer

 Note 

To  successfully  complete  the  installation  of  the  PM320E  USB  driver  you  must  have
administrator privileges on the PC which you are performing the installation.

Prior  to  connecting  the  PM320E  to  the  PC,  please  insert  the  CD  that  is  shipped  with  the
instrument  and  install  the  PM320E  drivers.  When  the  following  message  appears  after  the
installation,  you  also  need  to  install  NI-VISA  form  the  distribution  CD  or  from  the  National
Instruments web site:

After the software is installed successfully, connect the PM320E to a USB port of your PC. 
The PC will find sequentially a PM320E and a DFU device. Please follow the instructions of the
dialog screens and allow the installation.

4.2   PM320E Utility Software

The  PM320E  comes  with  a  utility  software  that  easily  enables  operating  the  PM320E  and
visualizing  and  logging  measurement  data.  The  software  is  written  in  LabVIEW  8.5  and  can
either be installed from the CD as executable where LabVIEW  isn’t required on the PC; or can
be  run  with  LabVIEW  8.5  or  higher.  In  any  case  it  is  necessary  to  install  the  drivers  as
described in chapter 

Connecting a Computer

.

The  source  code  of  the  application  is  included  on  the  CD  and  can  be  used  to  build  own
applications or to modify the utility program to customer requirements.

After  launching  the  PM320E  utility  program  it  will  automatically  scan  the  USB  interface  for
connected PM320E series devices. Select the desired PM320E device and press o.k.
